Jelly-Fish 45 Habitat: Captain Nemo Wants One

The main structural component of the Jelly-Fish 45 habitat is plastic reinforced by incorporated fiberglass; the submarine globe is made from acrylic with a high compressive resistance.

It's overall dimensions are ten meters high with a diameter of fifteen meters. The Jelly-Fish 45 would allow inhabitants to view sea creatures above and below the water.

It consists of five levels connected by a spiral staircase. The top level is 5.6 metres above the sea level and has been kept for study rooms. The next lower level is situated at 3.5 metres above the sea level and contains the night time zone while the next lower level at 1.4 metres contains the daytime zone with a kitchen and bathrooms. The lowest living level at 0.8 metres above the sea level is semi-submerged and has been kept for the guest room, bathroom and technical spaces.

I really think that Captain Nemo (of the Nautilus, of course) would have been pleased with the entire programme outlined by Giancarlo Zema. Consider, if you will, the well-appointed saloon of the Nautilus:

Suddenly light broke at each side of the saloon, through two oblong openings.
The liquid mass appeared vividly lit up by the electric gleam. Two crystal
plates separated us from the sea. At first I trembled at the thought that
this frail partition might break, but strong bands of copper bound them,
giving an almost infinite power of resistance.

The sea was distinctly visible for a mile all round the Nautilus.
What a spectacle! What pen can describe it? Who could paint
the effects of the light through those transparent sheets of water,
and the softness of the successive gradations from the lower
to the superior strata of the ocean?

Nearly every day, for some time, the panels of the drawing-room were opened,
and we were never tired of penetrating the mysteries of the submarine world.
